                         DISTRIBUTION AGREEMENT BETWEEN

                 COLLAGEN CORPORATION AND LEDERLE (JAPAN), LTD.

         This Agreement is made as of January 1, 1996 between COLLAGEN

         Collagen is in the business of developing, manufacturing and marketing
a variety of biomedical products derived from highly purified animal source
collagen protein, including Zyderm(R) and Zyplast(R) Collagen Implants which
are used for dermal augmentation and the correction of skin contour

prolong the grant of exclusive distribution rights for Zyderm(R) and Zyplast(R)
Collagen Implants in Japan on the terms and conditions set forth below for an
interim period of eighteen (18) months, during which time the parties will
study the possible formation of a jointly owned company in Japan for the sales
and marketing of these products and future products of Collagen Inc.

         In consideration of the mutual promises contained herein, Collagen and
Distributor agree as follows:

1.      DEFINITIONS:  As used in this Agreement:

                 are developed and marketed by Collagen during the term of this

                 Distributor retains its exclusive distribution rights for the
                 Products in the Territory, Collagen shall not itself

                 Distributor shall be required to use Collagen's trademark with
                 respect to all sales of the Products.  Such trademark license
                 shall continue in effect for the Territory while Distributor

                 title and interest to Collagen's trademark (except the right
                 to use such trademark set forth herein) shall remain with
                 Collagen.  Distributor shall not have the right to use
                 Collagen's name in any advertising or promotion or otherwise
                 without Collagen's prior written consent.  Upon Distributor's
                 request Collagen shall at its expense file trademark
                 registrations in the Territory.

        (d)      New Products:  If Collagen at any time within the lifetime of
                 this Agreement or any renewals thereof, develops other

                 proposed products in broad outline at as early a date as
                 possible and, in any event, not later than application in the
                 United States by Collagen for an Investigational New Drug or
                 Investigational Device Exemption (IND or IDE).  Collagen
                 shall, not later than the application for such IND or IDE in
                 the United States, offer Distributor the exclusive
                 distribution rights for such new products in the Territory,
                 providing a draft of the proposed distribution agreement.
                 Collagen shall also supply additional information to
                 Distributor concerning such new product as may be reasonably
                 necessary in Collagen's judgment and as may be requested by
                 Distributor to enable Distributor to make a reasoned decision
                 as to acceptance of Collagen's offer setting forth the terms
                 on which Collagen is willing to grant distribution rights for
                 such proposed products.

                 distribution agreement for such products within ninety (90)
                 days after Distributor's receipt of such draft, Collagen shall
                 be free to market such new products in the Territory itself or
                 through third parties.

                 signed up to a maximum of * of the US list price as at

                 hold Distributor harmless from any and all liability, causes
                 of action, damages and/or judgments, including but not limited
                 to attorney's fees, costs and expenses, which may arise out or
                 due to Collagen's actions in not manufacturing the Products
                 for Distributor in accordance with applicable U.S. Food and
                 Drug Administration ("FDA") rules and regulations and/or in
                 accordance with the IDE/PMA filed and amended by Collagen with
                 respect to the Products which have been approved by the FDA.
                 Collagen will provide, when requested by Distributor,
                 certification that to the best of its knowledge it is in
                 compliance with U.S. laws, statutes, rules, regulations and

                 with Distributor and will work with Distributor to insure
                 Collagen's obligations under this Agreement with regard to

                 shall be not obligated to pay for Products with any claimed
                 deficiencies or defects until such claims are resolved.  In
                 the event Collagen agrees that such defect in quality and/or
                 quantity are its responsibility, then Collagen shall promptly
                 and without charge to Distributor make up for such deficiency
                 and/or replace such defective Products with the Products
                 meeting specifications for Products.  Collagen shall bear the
                 costs of return of such defective Products to Collagen.

                 OR IMPLIED, WITH RESPECT TO THE PRODUCTS, INCLUDING WITHOUT
                 LIMITATION ANY WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A
                 PARTICULAR PURPOSE.

8.      DEFENSE OF LEGAL ACTIONS AND INDEMNIFICATION:

        (a)      Legal Actions:  Distributor agrees that Collagen shall have
                 the right to defend, or at its option to settle, any claim,
                 suit or proceeding brought against Distributor or its
                 customers on the issue of infringement of any United States or
                 foreign patent or trademark by reason of the Products sold
                 hereunder or the use thereof, subject to the limitations
                 hereinafter set forth.  Collagen shall have sole control of
                 any such action or settlement negotiations, and Collagen
                 agrees to pay, subject to the limitations hereinafter set
                 forth, any final judgment entered against Distributor or its
                 customers on such issue.  Distributor agrees that Collagen at
                 its sole option shall be relieved of the foregoing obligations
                 unless Distributor or its customers notifies Collagen in
                 writing within fifteen (15) days after it becomes aware of any
                 such claim, suit or proceeding and gives Collagen authority to
                 proceed as contemplated herein, and, at Collagen's expense,
                 gives Collagen proper and full information and assistance to
                 settle and/or defend such claim, suit or proceeding.
                 Notwithstanding the foregoing, Collagen assumes no liability
                 for any modification or combination of the Products with other
                 products or for any unauthorized or improper use or
                 application of the Products.

        (b)      Indemnification:  Collagen and Distributor each agree to
                 indemnify and hold the other party harmless from and against
                 any and all claims made by any person or entity arising out of
                 the manufacturing, testing, marketing, distribution and sale
                 of the Products, where and to such extent the damages are
                 alleged to have been caused by the fault of such party or its
                 employees or agents.  Collagen hereby indemnifies and holds
                 Distributor harmless from and against any and all claims made
                 against Distributor where and to the extent that damages are
                 alleged to have been caused by previously unknown or
                 undetected adverse effects or counterindications disclosed by
                 Collagen in its package insert (as updated from time to time)
                 or in U.S.  registration applications for the Products
                 provided to Distributor or as Collagen may otherwise notify
                 Distributor from time to time without any fault of
                 Distributor.
